Better way to do this? (bash scripting)

I hope this isn't considered too far OT, but perhaps someone will find
this useful.

I wrote the attached scripts, which I place in /etc/profile.d/, in order
to get quicker access to the original-package and Cygwin-specific
documentation.  (pkgdoc and cygdoc respectively)

What I wanted to know is:

1) is there a better and/or more precise way of searching for the file?
2) is there a better and/or more precise way of verifying that there's
actually such a file to feed to less, instead of calling find twice?

Thanks,

Yaakov
